This study investigated the demographic, intrapersonal, and organizational factors associated with burnout among a population of school counselors in the northeastern United States (n = 78). Three hierarchical regression analyses were completed to determine the amount of variance that each cluster contributed to the 3 subscales on the Maslach Burnout Inventory‐Educators Survey (MBI‐ES; C. M. Maslach, S. E. Jackson, & M. P. Leiter, 1996): Emotional Exhaustion, Depersonalization, and Personal Accomplishment. The final models accounted for 45%, 30%, and 42% of the overall variation on each subscale, respectively.  相似文献

Social and Economic Exchange: Construct Development and Validation   总被引:3,自引:0,他引:3  
This study examined the economic and social exchanges between employee and employer within a model in which perceived organizational support and affective and continuance commitment served as predictors and performance, altruism citizenship behavior, absence, and lateness served as outcomes. Two samples were used. 384 master of business administration students participated in Study 1, and Study 2 consisted of 181 aerospace employees and their managers, working for a single organization. Both studies supported the distinctiveness between economic and social exchanges. Study 2 showed the overall fit of the proposed model was adequate, though only social exchange, and not economic exchange, directly predicted the performance outcomes. These results suggest the importance of perceived exchanges between employee and employer.  相似文献

Previous research has uncovered links between generalized distrust and preferences for competitive (vs. cooperative) action. However, based on individuals' tendency to hold consistent attitudes and to believe that their own political preferences are morally legitimate, it was hypothesized that the direction of the relationship between distrust and competitive foreign policy preferences would depend on which category individuals had in mind: Americans or people. Two correlational studies with American participants were consistent with this hypothesis. Study 1 showed that distrust in Americans versus people had qualitatively different relationships with support for competitive policy preferences (i.e., immigration control, militaristic action). Study 2 found that when the covariance between distrust in Americans and people was controlled, distrust in Americans predicted opposition to torture of suspected terrorists, whereas distrust in people predicted support for torture of suspected terrorists. Moreover, individual discrepancies between distrust in Americans versus people uniquely predicted support for torture. Finally, mediational analyses in both studies indicated that political conservatism explained the effects between distrust in Americans versus people and competitive policy preferences. It is argued that distrust in Americans and distrust in people are distinct but complementary bases of Americans' moral-political reasoning.  相似文献

We investigated to what extent participants can acquire the mastery of an auditory-substitution-of-vision device ('The vOICe') using dynamic tasks in a three-dimensional environment. After extensive training, participants took part in four experiments. In the first experiment we explored locomotion and localisation abilities. Participants, blindfolded and equipped with the device, had to localise a target by moving a hand-held camera, walk towards the target, and point at it. In the second experiment, we studied the localisation ability in a constrained pointing task. In the third experiment we explored participants' ability to recognise natural objects via their auditory rendering. In the fourth experiment we tested the ability of participants to discriminate objects belonging to the same category. We analysed participants' performance from both an objective and a subjective point of view. The results showed that participants, through sensorimotor interactions with the perceptual scene while using the hand-held camera, were able to make use of the auditory stimulation to obtain the information necessary for locomotor guidance, localisation, and pointing, as well as for object recognition. Furthermore, analysis from a subjective perspective yielded insights into participants' qualitative experience and into the strategies they used to master the device, and thus to pass from a kind of deductive reasoning to a form of immediate apprehension of what is being perceived.  相似文献

To study action monitoring in anorexia nervosa, behavioral and EEG measures were obtained in underweight anorexia nervosa patients (n=17) and matched healthy controls (n=19) while performing a speeded choice-reaction task. Our main measures of interest were questionnaire outcomes, reaction times, error rates, and the error-related negativity ERP component. Questionnaire and behavioral results indicated increased perfectionism in patients with anorexia nervosa. In line with their perfectionism and controlled response style patients made significantly less errors than controls. However, when controlling for this difference in error rates, the EEG results demonstrated a reduced error-related negativity in the patient group. These seemingly contradictory outcomes of improved performance and reduced error monitoring are discussed in relation with indications of anterior cingulate cortex hypoactivity in anorexia nervosa patients.  相似文献

Whenever we explore a simulated environment, the sensorimotor interactions that underlie our perception of space may be modified. We investigated the conditions under which it is possible to acquire the mastery of new sensorimotor laws and thereby to infer new perceptual spaces. A computer interface, based on the principles of minimalist sensory-substitution devices, was designed to enable different possible links between a user's actions (manipulation of a mouse and/or keys of a keyboard) and the resulting pattern of sensory stimulation (visual or auditory) to be established. The interface generated an all-or-none stimulus whose activation varied as a function of the participant's exploration of a hidden form. In this study we addressed the following questions: What are the conditions necessary for participants to understand their actions as constituting a displacement in a simulated space? What are the conditions required for participants to conceive of sensations as originating from the encounter with an object situated in this space? Finally, what are the conditions required for participants to recognise forms within this space? The results of the two experiments reported here show that, under certain conditions, participants can interpret the new sensorimotor laws as movements in a new perceptual space and can recognise simple geometric forms, and that this occurs no matter whether the sensory stimulation is presented in the visual or auditory modality.  相似文献
